msrENsrNG DEVICE.

Application led August 271921, SerialA This invention relates to dispensing devices; and more particularly to devices such as those used as fire extinguishers or for spraying or dispensing liquids under pressure.

In dispensing devices of the type in con nection with which my` invention has been developed a liquid is contained in the receptacle and is forced out when released by means of pressure exerted by a compressed Huid such as compressed air. It will be understood that in such'devices-the discharging orifice must be very effectively sealed to prevent the escape of the compressed fluid or liquid. Furthermore, means must be provided for charging tlre receptacle with the compressed air and for effectively sealing the receptacle after the charge has been completed without permitting the compressed iiuid or liquid to escape.

With these problems in mind, one of the objects of the invention is to provide simple and effective sealing means for a dispensing device.

Another object of the invention is to provide sim le and easily operable means whereby t e receptacle may be charged with compressed Huid such as a1r.

Another object of the invention is to provide simple and easily operable discharge control means, this control means being so constructed and arranged that it will not interfere lwith the proper directing of the stream from the receptacle.

Another object-of the invention is to provide means lor insuring the complete discharge of the liquid in the receptacle.

Another object of the inventionis to provide charging and discharging'means that may be easily and quickly attached to and detached from the receptacle.

Another object of the invention is to provide means for insuring a constant and steady iiow of liquid from the receptacle and to prevent the stream from becoming clogged or stopped by foreign matter.

. Another object of the invention is to provide a dispensing device and charging and discharging attachments therefor' that will be simple in construction, comprise few parts, may be economically manufactured and may be. easily and quickly operated.

Further objects will appear from the following specification taken in connection No. 496,044. Renewed January 87, 1927.

The invention briefly described comprises a receptacle having means for conducting the liquid to and from the bottom thereof and having a neck extending outwardly from one end thereof. The neck is apertured to receive the liquid conducting means referred to and is recessed to receive a sealing member by means of which the opening through the neck may be closed. Means is provided for actuating or moving the sealing member to sealing position and for retaining the member in that position. Charging means in the form of a charging attachnient is provided and is adapted to be coupled to the neck and has a conduit for conducting the compressed fluid such as air to the neck opening. This attachment also has means whereby the sealing member actuating means may be actuated to effect the sealing of the nec opening.

These parts are so constructed and arranged that the sealing disc may be assembled with the other parts before the charging attachment is coupled to the neck, but in such a manner that the sealing member will not prevent the passage of the com the disc 'pressed air into the receptacle.

elevation of a dis- I `and projecting outwardly from one end.

The neckv 21 has formed vtherein al recess 22 which communicates with an opening 23 and the opening leads into the receptacle. The neck also has a small opening 24 which extends from the interior of the receptacle to the recess V22 an'd'forms an air vent for permitting the escape of air from the receptacle when the receptacle is receiving the liquid.

As Will be hereinafter described the liquid in this type of dispensing device is forced out bypressure exerted on the surface of the liquid and in order to insure the complete discharge of the receptacle a conduit 25 is secured in the opening 23 and extends as shown at 26 to a position adjacent the closed end 27 of the receptacle. l

A washer 28 of elastic material, such as rubber, is inserted in the bottom of the re- 'cess 22 and has an aperture 29 registering with the opening 23 in the neck.

. For the purpose of sealing the neck discharge opening a fiat disc 30, having a diameterslightly less than the diameter of the recess, is inserted in this recess above the washer 28. The disc 30 has downwardly projecting portions 31 preferably pressed i out of the material of the disc and these portions 31 engage the upper surface of the washer 28 and holdthe disc in spaced relation with respect to the washer when the parts are assembled and before the disc is moved to sealing position.

In order to move the disc to sealing position and to retain it in that position a threaded plug 32 is inserted in the ,recess 22, the latter being also threaded to receive the plug. The plug 32 has a central aperture 33 preferably square in cross section for a purpose hereinafter described. The plug also has a plurality of radial grooves 34 on its under surface communicating with the aperture 33 and extendi g to the periphery of the plug.

I will next describe the charging attachment. This attachment comprises a socket -35 which isv adapted to be placed over the neck 21 and is provided with inwardly projecting pins 36 which coact with cams 37 formed on the neck 21 in retaining the socket in engagement with the neck. As

shown particularly in Fig. 4 the cams 37 l ber is inserted in the inner end of the socket 35 and when the charging attachmentis placed over the neck and rotated so that the pins 36 will engage the cams 37 the attachment and socket with the packing will be forced into tight engagement with the outerend 40 of the neck, thereby preventing any escape of the compresed air.

The charging attachment has formed therein a recess 41 which communicates with the' recess in the socket 35 and the attachment also has a. laterally extending conduit 42 communicating with the recess 4l.

In order to control and rotate the plug 32 when the receptacle has been charged with compressed air or iuid, the charging attachment 1s provided with 'a stud 43 square in cross section and corresponding in section to the square aperture 33 in the plug 32. The end of this stud also has a plurality of longitudinal grooves 44 for permitting the passage of air through the plug 32. A disc 45 is secured to the opposite end of the stud and a stem 46 is secured to the disc and extends through an opening 47 and a recess 48 formed in the discharging attachment. A handle 49 is secured to the free end of` the stem 4'6 and a spring 50 is mounted in the of the charging attachment and at its opposite end a portion 52 of the handle. This spring retains the disc 45 in tight engagement with a washer 53 which `is positioned between the disc and one side of the wall 51 through which the stem 46 extends. washer, therefore, effectively prevents air from escaping from the charging attachment through the opening 47. v

The operation of the charging attachment will now be briefly described. The parts are assembled in the manner shown in Fig. 1 and the source of supply of compressed air is connected to the conduit 42. The air then enters through this conduit and passes through the recess 41 and grooves 44, opening 33 and grooves 34 and plug 32 around the disc 30 and through the opening 23 and i conduit 25 in to the receptacle. When a sufficient charge has been received, the operator by turning the handle 49 rotates the plug 32, thereby forcing thesealing disc 30 into sealing engagement with the rubber Washer 28. this position being shown in Fig. 2.

. Referring t0 Fig. 2, I will now describe the'discharging attachment. This attachment comprises a socket 60 which vcorresponds to socket 35 of the charging attachment shown in ig. 1 and is coupled to the neck 21 in the same manner as the socket 35. The discharging attachment also has a The lill) recess 61 corresponding to the recess 41 in Fig. 1. A disc 62 is positioned in the recess 6l and has secured thereto a stem 63 which extends through an opening 64 located in a wall 65 between the recess 6.1 and an oppositely extending.,r recess G6. A washer (i7 preferably of rubber or some equivalent material is seated at the inner end of the recess 61 and between the disc 62 and the wall 65. A button 68 is secured to the free end of the stem 63 and a Spring 69 surrounds the stem and is positioned between the but-ton and the inner end of the recess 66. The spring, therefore, exerts an outward pressure on `the button which is communicated to the steln and to the disc 62. This pressure forces the disc 62 against the washer 67 pressing the washer against the inner end of the recess 61, thereby preventing any escape lof the compressed air or liquid5 through the opening 64. v

For the purpose of piercing or breaking the sealing plate 30, a spike 70 is secured to or formed integral with the disc 62 and extends downwardly in alinement with the opening 33 in the plug 32. A conduit 71 communicates with the recess 61 and a flexible hose 72 connects the conduit 71 with a nozzle 73.

The nozzle 73 comprises two parts, 7 4 and 75, which are shown in Fig. 8 as screwthreaded. The member 74 is concaved as shown at 76 and the member 75 has a concaved registering ortion 77. These two coneaved portions orm a reservoir for the llquid being discharged.

In order to interrupt the passage of any foreign matter through the nozzle, a. screen 78 is interposed between the lsections 74'and 7 5 of the nozzle and this screen as shown in Fig. 8 is positioned within the reservoir formed by the concaved port-ions 7 6 and 77. When the device is used as a 4fire extinguisher or for spraying. it is, of course, desirable that the stream be scattered or spread as it issues from the nozzle and for this purpose the outlet end of the nozzle is reduced in section .as shown at 79. Because of this small cross section it is very desirable that any foreign matter in the stream be stopped before reaching the outlet 79 and this object is effectively attained by means of the screen4 78. The screen also assists in insuring and maintaining a steady and constant flow of liquid through the nozzle.

The operation of the discharging attachment will now be briefly set forth. With the'nozzle in place as shown in Fig. 2 the operator to break the seal merely strikes a sudden blow on the button 68, whereupon the sealing disc 30 will be pierced. The compressed fluid or air within the receptacle will then force the liquid out through the.` conduit 25 through the opening 33 in the plug through the recess 61 and conduit 71, ilex-A ible hose 72 and nozzle 73. Particular attention is directed to the fact that after the sealing plate has been pierced or punctured the operators entire attention can be given to the proper ldirection of the stream and in the case of fire extinguishers this, of course,

thatthe invention is capable of modification.

and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claims.
